000009537 520__ $$2eng$$aSeismic responses of large dimensional structures excited by spatially varying ground motions are studied by many researchers. Most of previous studies assumed a flat site and uniform site properties. Studies of the combined site amplification and ground motion spatial variation effects on structural responses are limited. This paper investigates the effects of spatially varying ground motions on responses of a PC bridge frame located at a canyon site in Perth, Western Australia. The ground motions at base rock are assumed to have the same intensity but vary spatially. They are modelled with an earthquake ground motion attenuation model derived for Western Australia and a coherency loss function. Site amplification effect is modelled by an explicit transfer function based on one dimensional wave propagation theory. Quasi-static, dynamic and total responses of the bridge frame are calculated with the stochastic method. Numerical results of various response quantities to spatial ground motions are presented. The importance of the site and ground motion spatial variation effect on bridge frame responses is highlighted.
